OK everyone don't know if I have the description correct but I'm looking for a tail panel for a 70 Cutlass Supreme. Does any one make a repo of these?

 

Do you mean 'Sail Panel'? Best thing you can do is take a picture of the car and circle the part you're looking for.

Just based on your description it could be:
left or right quarter panel,
trunk drop downs
trunk floors
CS quarter panel extensions
Rear window deck extension

ok so how do you post a pic? Its the panels that go across the trunk where your trunk latch mounts. there is the top one that has your seal groove in it and the one underneath that , that your rear body mounts rest on

 

I don't think they're being repop'ed. You'll likely have to create a parts wanted thread and find a used one that's not rusty/rotten.

There's a few ways to post pictures. Try this one suggested by Allan.

Not being repro'd. Good used is your only option.
